A thin drawdown of walnut oil requires considerably more patience than cold-pressed linseed, yet its resistance to yellowing justifies the delay. On borosilicate glass, the film remains tacky long after the lighter esters evaporate, polymerizing at an unhurried rate under afternoon warmth. Synthetic driers could accelerate surface cure within hours, but rapid skinning risks trapping fluid beneath an uneven crust. Letting ambient air dictate oxidation remains the only reliable route to structural uniformity.
